. UNITED STATES PATENT OFFICE HARRY LAN'DS IEDEL, OF CINCINNATI, OH IO,ASSIGNOR, BY MESNE ASSIGNMENTS, TO REMINGTON BAND INC., 01 NEW YORK, N.Y., A. CORPORATION OF DELAWARE ADDING MACHINE Application filed April20,

This invention relates to printing-adding machines designed especiallyfor co -operating with perforated record cards of the well knownHollerith type, in which the print- 5111 and adding records areindicated by sultably spaced perforations in said cards ;which areusually provided with a series of vertical rows of imprinted digits fromO to'9 arran ed in several vertical columns, 10 each of Sn cient, caacity to accommodate the required data. i-Iowever, the printing on saidcards is merely for the purpose of facilitating a proper locating of theperforations, and said printing may be omitted with the successfuloperation of the mac ine ofthe present invention.

The object of the present invention is to simplify tabulating machinesof the well known Powers and Hollerith types and the work to beperformed thereon, by providing a compact unified adding machine notonly capable of performing the work now done by such machines, but amuch greater variety of work of the same general character.

Machines of the kind now in use, as exemplified by the Powers andHollerith t pes, in so far as their adding and printing unctions areconcerned, comprise associated separate adding and printing groups, eachof sufficient capacity to accommodate the maximum possible requirementsof such a group unit, with the result that in normal operation many ofthe adding and printing elements in any particular group unit willrarely be called into service.

This method of associating several separate full capacity adding andprinting group units for use in a single tabulating machine not onlygreatly increases the manufacturing cost of such machines but-at thesame time reduces their efliciency. It will be obvious to thoseskilledin the art that such machines must of necessit be more bulky and a atthe same time less exible than a single unified machine so constructedas to permit the operator himself to establish such a grouping of'theseveral printing and adding instrumentalities as occasion may war- 1923.Serial No. 633,374.

rant. It is also obvious that such a unified machine, because of itscompactness, and the consequent compactness of the printed columns, willeffect a considerable saving in paper and at the same time produce moresi htly and desirable records than machines 0 the type now on themarket. A

In illustrating a preferable exemplification of the principles of myinvention I have used for performing the adding and printing functionsthe commercially well known Dalton mechanisms, with necessary changestherein, together with setting up mechanisms of the well known Powerstype, with necessary changes therein; but it will be obvious to thoseskilled in the art that other adding and printing mechanisms may beadopted and used without in any way departing from the spirit of myinvention.

In using machines of the general character of the one to which thisinvention is directed, it is the usual practice to perforate previouslydesigned record cards at the proper digit in each ordinal row in thecolumns representing data to be printed and added, or printed only,after which said cards are preferably automatically fed into the addingor tabulating machine in such a manner as to cause the holes thuspunched to co-operate either through electrical contacts like that of.the Hollerith type, or through mechanical means like that of the Powerstype, with the adding or tabulating mechanisms to print and add theitems indicated by the holes previously punched, or to add only whenprinting is not required, or print only when adding is not required. Insuch machines the perforated cards are fed into the analyzing portionthereof in position to co-operate with a series of plungers or likemechanical, pneumatic or electrical devices in register with the rows ofdigits in the record card. Upon release of the entire group of plungersor othencooperative devices, those which are in alignment withperforations will co-operate effectively to actuate the required numberof stops or other controlling mechanism in 'the printing andaccumulating portions of the machine to cause it to print and add theprint only as the case may be.

Cards for use in connection with machines of this character are usuallyperforated in such a manner as to provide columns which contain rows ofdigits representing num bers to be added and accumulated, and alsocolumns of digits indicating dates, stock sizes and the like to berecorded but not added. 7

From the foregoing it will be seen that provision must be made foradjusting machines of the character under consideration according tosome grouping scheme which will confine the adding and accumulating ofnumbers to the particular columns requiring such adding andaccumulating; and at the same time-the machine must be provided withmechanismto permit the operator at will to select those columns in whichprinting only is required.

It is evident that a column containing, for example, four rows of digitsto be accumulated and totalized may require five or more adding wheelsto accommodate the total of such column. Therefore, if the nexthigher-order adding wheel or wheels are simultaneously required for likeservice in an adjoining column, a proper functioning of the mechanismwill be impossible.

In machines of the character now on the market, such as the Powers andHollerith machines, effort has been made to meet the commercialrequirements by arranging the series of separate and distinct adding andprinting group units side by side with mechanism provided for enablingthe operator at will to adjust an entire group-unit or units either forservice in columns to be added and printed or for columns which requireprinting only. This adjusting by group-units is objectionable by reasonof the fact that each group-unit must within itself afford the necessarynumber of mechanisms to meet the greatest possible requirements whichmay be imposed upon it, whereas, in the actual operation of the machine,any particular group-unit may be utilized to but a fraction of itsmaximum capacity, so that in the machine as a whole a large number ofthe printing and adding instrumentalities occasionally re uired to meetall possible contingencies won (1 remain idle in any particular case. Itis obvious, therefore, that the cost of building such machines isexcessive, besides which the printing columns are widely spaced becauseof the provision of surplus idle mechanism, especially when small itemsare listed, which is objectionable.-

Machines of this character are further objectionable in that they lackthe necessary flexibility to permit the operator to utilize any grouparrangement other than that specifically arranged for by themanufacturer, whereas, in the machine of my invention, the operator atwill may arrange the individual adding and printing mechanisms into suchcombinations as may be desired, each individual adding and printingtrain, of elements being adapted for use either in 'its full adding andprinting capacity or in .which they are associated. This arrangementmakes it unnecessary to provide special surplus adding wheels toaccommodate an extended total, and enables the several columns to beprinted in close relation to one another, and imposes no limitationwhatsoever upon the operator in the group-arranging of his mechanismsother than that of avoiding juxtaposed relation of two adding columns incases where an extended total may result from the accumulation of items.

In the present machine, which in the form shown employs printingsectors, racks, and adding wheels, it will be understood that one eachof such instrumentalities associated in the printing and accumulating ofa single digit will be referred to as a printing and .adding train, andwith this understanding it is proper to state that the present inventionmarks a distinct improvement over earlier constructions, in that eachtrain is a counterpart of every other, in construction, function andmode of operation, across the entire width of the machine, so that by amultiplication of trains, which lie in very close relation to oneanother, the capacity of the machine may be indefinitely extended, andthat howsoever great may be the aggregate capacity of the machine, eachtrain may be thrown into group arrangement with any other train, eitherfor the purpose of printing and adding, or for the purpose of printingalone. That is to say, each train in the entire set may be adjusted toperform its full capacity of printing and adding, in which case the macline will present but a single printing and adding group; or each trainmay be adjusted to print only as a constituent in a single printinggroup, or, as is, usually the case, the entire series of trains may bedivided into a number of groups, each group comprising as many trains asmay be required, thereby affording a practically unlimited field ofadjustment in group arrangement without restriction other than that ofproviding for the accommodation of an extended total.

, The present invention is shown as mount ed upon a frame 10 whichcontains a plunger mechanism for direct co-operation with the perforatedcards, of the general character shown in the Powers Patent No.1,236,481.

The frame 10 supports a base 11 from which protrude a series of pushrods 12 adapted to be elevated by those plungers of the entire number ofplungers which are released through the perforations in the record card.It is evident that the push pins must correspond in number andarrangement with the plungers, and that a plunger and push pin ,must beprovided for each potential perforation in the record card.

Immediately above such push pin is located avertically slidable stop 13of the stops being-arranged 'in an arcuate line, as indicated in Fig. 1.In addition tothe .movable stops, a terminal series of fixed stops 15.is provided for ultimately arresting movements o'f any type" carrierwhich is free to move to the ultimate position. These rows of stops areprovided to control the jextenfi of movement of a' series of closelypositioned uniformly spaced type carriers 16 of sector shape, which typecar-- .riers depend from and are freely mounted upon a rock shaft 17,each type sector being provided with a. tail piece .18 which is engagedby a spring 19 secured at its lower end to across bar 20, thearrangement belng such thatwhen the ty e sectors are'free' to movearound the sha t 17 as an axle they will move to the extent permitted bythe rows of 'stops 13 with which the type sectors co-operate. Eachsectoris provided with a heel 21 arranged to engage with any stop in thecorresponding row which ma be elevated prior to the release of the banof type sectors.

closey spaced adding wheels 26 mounted upon a continuously extendingunbroken shaft 26 (Fig. 5) the number of adding wheels being equal tothe number of racks and type sectors. The racks, like the type sectors,are freely mounted upon the rock shaft 17 and are adapted to move withthe .type sectors when latched thereto by the mechanism now to bedescribed. This mechanism comprises, for each type sector and rack, astop pin 27 (Figs; 1 and 3) laterally extending from the rack bar andadapted to be engaged by 'a hooked latch member 28 pivoted at the point29 to the associated type sector, and adapted to be held in depressedposition" by the tension of the spring 30.

The tail end of each latch member 28 occupies a position immediatelyabove the i forward arm 31 of a bell crank lever 32, a series of levers32 being mounted u on a' cross rod 33 carried between apair 0 connectedside plates 34 which constitute a swinging frame mounted upon atransverse shaft 35. The lower arm of each bell crank lever lies in aosition to be engaged I) a lug 36 upstanding froma sliding key M 37having at its end a finger button 38 containing a proper indicatingnumeral or sign. A depression of any key has the effect of rocking theassociated bell fcrank lever against'the tension ofa spring 39 andelevating the associated latch; 28 to unlatch the type sector from theassociated rack bar, so that the sector only will move out under tensionof the spring 19 when the handle of the machine is 0 rated and the shaft17 rocked. The pin anchoring the spring 30 to the type sector limits thedownward The keys 38 correspond in number to the number of rows of diits which the machine is designed to han 1e, as, for instance, cforty-'five rows, andthe arrangement is such that the operatormayjdepress the requisite' number 0 keys required to effectuate agrouping of the mechanisms into addin non-addmg groups in conformitywith scheme observedin groupin the. columns on the cards which themachine is designed to handle, subject to the, requirement that theseveral adding groups must associate and the

j with non-adding groups, which latter furassociated key. All of thedetents are pivoted upon a cross rod 43, and each detent is heldelevated by a spring 44, as best shown in Fig. 3. The arrangement issuch as to hold the key in either the normal or depressed position ofadjustment. In order to effect a restoration of all of the keys tonormal osition a cross bail bar 45 is provided, which overlies all ofthe detents, and is carried at opposite ends by a pair of swinging arms46which are pivoted upon the protruding ends of the cross rod 43, slots47 being cut in the plates. 34 to permit a swinging movement of the bailbar 45. A' depression of the arms causes a retraction of the detents anda simultaneous release of all of the depressed key bars, which arerestored b the tension of the springs 39 acting throug the bank of bellcranks 32.

To secure and print a total, the following mechanism is utilized: Atotal link 48 (Fig. l), is provided which is pivoted at the point 49 toa total lever 50 of hell crank formation, which total lever is pivotedon a shaft 51 and operated b a link 51a (Figs. 7 and 8). The rear end 0I the total link occupies a position immediately in advance of a stud 52(see also Fi 2), inwardly extending from the left han plate 34, so thatwhen the total lever 50 is thrust inwardly or rearwardly the framecomprising theplates 34 and all mechanism carried thereby will be rocked'to the rear, thereby releasing such of the latches 28 as have beenengaged and rocked by the depression of the respective keys. Thlsrelease of the bell cranks will permit the associated latches 28 tofall, thereby latching together the entire group of rack bars with theassociated type sectors, so that all of the rack bars will be preparedto move forward with the type bars in the taking of totals. The usualmechanism, shown in Figs. 7, 8 and 9 under the control of the total linkis provided for lifting the bank of addingwheels into engagement withthe racks on the forward stroke of the racks, so that each adding wheelinto which a number has been introduced permits an advance of theengaged rack to the degree required to restore the wheel to zeroposition, as is usual in adding wheel construction, which mechanism willnow be described.- v

The adding wheels 26 are mounted upon the shaft 26" the ends of whichare journa'led within the free ends of a pair of swinging arms A freelypivoted upon a cross rod B suitably mounted within inner supportingplates C. The protruding ends of the shaft such position as to bring theelevation F into A contact with the corresponding roller D.-

The shaft G, at the left end thereof, has slidably mounted thereon aslide plate I provided with an upper slot J which embraces the shaft Gand a lower slot K which embraces a stud L outstanding from the lowerend of the cam plate.

The slide plate is also provided with an obliquely disposed slot M whichreceives a pin N inwardly extending from a three-way arm 0 which ispivoted upon the end of the shaft G outside of the slide plate. Thearrangement is such that as the slide plate'is depressed, it will turnthe three-way arm in a clockwise direction from the position shown inFig. 7 to the position shown in Fig. 8.

The three-way arm is provided with a lower pin P and an upper pin Q, theformer being normally disposed as in Fig. 7', to be engaged by ashoulder R on a wipe pawl S carried by the free end of an arm T mountedupon the main shaft 57. The lower end of the wipe pawl is acted upon bya spring U which causes the free end of the wipe pawl to swing insubstantially parallel relation with the arm T when the main shaft isrotated on the forward stroke of the handle. The wipe pawl is furtherprovided with a shoulder V which co-acts with the pin Q on the returnmovement of the shaft.

Theslide plate I is ada ted to be depressed by the contact of tie lowerfinger of a. bell crank lever W mounted upon a shaft, the upper end ofthe lever being engaged by a pin Y carried by the total link 48. Thearrangement of these parts is such that when the total link is moved tothe rear (left in Figs. 7 and 8), the lower end of the bell crank leverW will act to depress the slide plate I from the position shown in Fig.7 to the position shown in Fig. 8. This will have the effect, throughthe action of the diagonally depressed slot M and pin N of turning thethree-arm lever clockwise from the position occupied in Fig. 7 to theposition occupied in Fig. 8.

-With the parts as in Fig. 7, when the main shaft is rotated clockwlse(Fig. 7) on the forward stroke of the handle, the shoulder R of the wipepawl will momentarily engage the lower pin P of the three-way lever, andimpart a partial rotation thereto which will be imparted to the camplates E, rocking them so as to bring} the elevated portions of the camaway from the rollers the three-arm lever and immediately lift theadding wheels into mesh with the rack so that on the return movement ofthe handle, the amount set up will be accumulated. \Vhen the total istaken,with the parts ad justed as in Fig. 8, the pin P will have beenlifted to a position such that the wipe pawl will swing under the studon the forward strokeof the operating handle, allowingthe adding wheelsto remain in mesh with the racks on the forward stroke. The

pin Q, however, in this adjustment, occupies a position such that uponthe return stroke it will be engaged by the shoulder V ofthe wipe pawland moved with it sufficiently to cause a reverse movement of the camswhich will allow the rollers D to ride down onto the depressed forwardedge of each cam,

thereby disengaging the adding wheels from the racks during thereturnmovement of the racks which will leave the machine clear. Near thetermination of the handle stroke on such clearing operation, the cams,which have been rocked rearwardly, will be re stored by the contact of afinger Z which swings with the arm against a stop pin Z on the left-handcam, which stop pin with the cams adjusted for clearing, will lie withinthe return path of the finger and be engaged thereby. i

The above parts are common to adding machines of the Dalton type and arenot special to the present invention, so that further descriptionthereof is deemed unnecessary. v

When, however, an amount has accumulated in a group which exceeds thecapacity of the wheels composing that group, then as thewheel of thehighest order in that group turns from its 9 to 0 point in the listingon an item, the carrying pawl 52, (Figs. 53nd 6), of the rack barimmediately to the left of it, in a non-adding group, is lifted and therack bar will move one step to the rear, causing the digit l-to becarried over from the adding roup into the next left adjacent adding 'weel to be accumulated as the highest figure in the total in a mannerconformable to the usual means provided in addingmachines for thecarrying of the accumulation from order to order, as, for instance, inthe Ho kins Patent No. 1,039,130. Thus "it is evi cut that the capacityof any adding group can be ,extended eyond thenormal capacity of thewheels provided in that group, by arranging the various groups of-datain columns which add and accumulate, and associated groups which recordwithout accumulating. V I f It will also be observed that by latchingall of the rack bars in preparation for a total, each rack bar andassociated sector is in condition to actively participate in therecording of a total. After a rack bar of a nonadding group hasfunctioned to carry an excess amount into its accumulating wheel, it isnecessary to restore the rack bar,

which has moved back one place under the tension of a spring 53, to itsnormal positiofi where it will be latched by the carrying pawl thatfunctions with it. This accomplished by two arms 54, (Figs. 1 and 2),which are freely pivoted at their upper ends on the shaft 17. The lowerends of the arms are connected by means of a transverse bail 55 just tothe rear of the rack bars and sectors, where it is held retracted by aspring 56. Each time tlie main shaft 57 is operated the rock shaft 17 isrocked by means of a link 58 which is connected to-an arm 59 on theshaft 17 and to the main shaft cam 60 at the point 61.

Each arm 23 on the shaft 17 is provided with a stud62 so positioned thatthe respective studs will come in, contact with the arms 54. just beforethe main shaft has completed its forward movement. This will have theeffect of driving the bail 55 far enough on each operation/of the mainshaft so that it carrying pawls 52 in the manner shown in the Hopkinspatent aforesaid.

- Ordinarily the heels 21 of the type sectors will limit against acipher stop 63, but upon the taking of a total these heels are under thecontrol of the accumulating wheels,' and means are provided for shiftingall the cipher stops to the side and out of the way of the sector heels.To effect this result the following mechanisms are provided Each cipherstop comprises an upstanding portion of a plate 64 provided at its forward and rear ends with fingers 65 extending through 'the adjacentportions of the frame 14, which fingers serve as pivots permitting thelateral swinging of the plate. The rear ends of all of the stop platesare engaged by a slide bar 66 which is provided with an outstanding stoppin 67 adapted to he engaged by the beveled cam surface 68 of a camblock 69 mounted on ashaft 70, which carries an arin 71 provided at itsfree end with a roller 72 which is adapted to be engaged by the beveledunder edge of a finger 73 which depends from the total link 48, so thatas the total link is moved rearwardly in preparation for the taking of atotalthe arm 71 will be moved downwardly and the shaft 70 with the camblock will be rocked in such a manner as to cause the beveled surface 68to bear against thepin 67 and thereby move the slide plate and with itthe rear ends of the stop plates to positions permitting the heels 21 toclear the cipher stops and advance to the point permitted by the addingwheels, which give up the accumulated movements, and restore to zeroposition.

In order to permit the type sectors to ad- 'vancepast the cipher stopsin listing items, each cipher stop plate is shouldered as indicated inFig. 4, and is spring pressed against a corresponding line of shouldersonthe associated row of digit stops, so that the elevation of any digitstop will swing the cipher stop bar to the side and allow the heel ofthe associated sector to clear the cipher stop and advance until itencounters the digit stop.

Afterv a total has been taken, and as the total link 48 moves forward toits normal posit-ion, springs 72, (Fig. 1), secured to the side plate 34cause the key control assembly to move forward, and those keys which aredepressed will again release the latches, so that the group arrangementof the mechanism will remain undisturbed by the taking of a total.

The operation of the machine may be briefly summarized as follows: Inpreparing the machine for recording and accumulating group operations,those keys are depressed which are necessary to divide the mechanisminto associated adding and recording groups 111 conformity with .thecolumn arrangement of the perforated cards. Thereafter the operation ofthe released plungers which enterthe perforations in the lower portionof the machine will effect a lifting of a correspondmg number of digitstops in the stop carriage in group arrangement. Thereafter, upon theoperating of the main shaft, all of the type sectors will move forwarduntil arrested by the upraised stops, and the hammers will be fired andthe items listed in group arrangement.

Upon the taking of a total those racks only will function which eitherco-operate directly with the adding wheels in an addmg group or arebrought into the accumulating operation to record a higher order thancan be accommodated in the adding group.

It is obvious that the machine of my invention herein describedaccommodates practically an unlimited variety of group arrangements ofthe individual adding and printing trains, since each of the keys, forty-five in number more or less, individually controls the extent of thefunctioning of the train with which it is associated, which train canthus be adjusted to conform to the functional requirements of theparticular group within which the train is included for the time being.That is to sa each train maybe adjusted to utilize its full functionalcapacity in adding and printing, or to utilize its reducedfunctionalcapacity where printing only is required, without, however, in any wayinterfering with the operation of the carrying mechanism in extendingthe total from order to order.

Although the mechanism illustrating one form of my invention has beendescribed with particularity, it is obvious that many modifications maybe introduced without departing from the principle of the invention.Thus, for example, in place of the push rods utilized for actuatin thestops under the control of previous y punched cards, other stopactuating mechanism might be utilized, either under the control ofpreviously prepared cards or similar prerecorded instrumentalities, orunder the control ofkeys which may be individually operated to set thestops in the required positions according to a group arrangementconformable to the setting of the group keys 38;

It is not, therefore, the intention to limit the invention to oneinwhich the stops are simultaneously set through the transference of arecord previously impressed on a card or the like, since the features ofthe present invention are available for use in nitial setting up ofrecords in the selves.
